文摘
It is described the simple design of a series of N,N¡ä,O,O¡ä-chiral ligands (elpaN-salen-H2), which represent a subset of the elpaN-type library of ligands based on ¦Â-1,2-d-glucodiamine. The corresponding Mn(III) complexes were examined in the asymmetric epoxidation of styrenes with satisfactory results, e.g. cis-¦Â-methylstyrene was functionalised in ees up to 88 % .
